At first a big thank you to Cetacea91, Daxianer, LaMulder and martl for their feedback and for providing test data!
This tools takes the gpx file with your found caches and collects the banners from the listings.
The banners are parsed from the "long_description" and for some special cases and for generating the link-tags we need the GC-Code and the url.
IMPORTANT: Since we also rearrange the banners for a more beautiful shape we need to get the size of all images, that could take a while, please be patient.
How to use this tool
You can either upload a single GPX-file (like the "my finds" file) or you can directly upload the zip file you get from Groundspeak. If you are not a premium member you can collect all GPX-Files of the caches you found manually and put them in a single zip. You can then upload this zip file and the tool will look into all of the contained GPX files and will collect all the banners from those who have one.
I found a bug or the tool behaves funny
If you found a bug, or you know, the tool does not find a banner please contact me. I cannot test with all caches and some banners are pretty hard to catch. You can find the contact email in the footer and in the imprint. It would be great, if you could provide the GPX or zip-file which triggered the wrong behaviour.
If you have any question or proposal for improvement we can also talk about it, of course.
